The theory of human nature in the Guodian Chu Slips which is thought to be the confucianist history document has received much attention and the researches have been too numerous to mention. While, the basic conceptions, such as, "Tian," "Ming," "Xing," and "Qing" still need further studies. From the Guodian Chu Slips, the conception of "Ming" and "Xing" belongs to the "Ben"(basic) field, which is born by the "Tian." But the conception of "Ming" and "Xing" is not a moral ontology "Qing" is born by the "Ren"(human being), belonging to the "Hua"(change) field. The Construction of the separation "Tian" and "Ren", the relation between the "Ben" and "Hua," the Emphasizing the naturally quality of "Xing," the understanding of the uncertainty of "Ming", all these are similar to the history documents of the Taoism. It shows that the Guodian Chu Slips has a close relation to the Taoism. It is the thoughts of Xun Zi that is more familiar to the Guodian Chu Slips, not the Mencius, in the pre-Qing period, as well as the Qin and Han dynasty.
